Well, there are brands out there selling pre-made raw diets, but I think you'll find that making your own is a *lot* less expensive.

I started off by buying whole ground chicken from Hare Today and mixing up batches to freeze, then moved to grinding the meat and bones at home, and now I buy fresh and feed whole-prey, which means I try as much as possible to simulate a whole animal: meat, bones and organs.

Based on what I've read and learned, it's important for cats with bladder problems to avoid raw diets that still contain grains or veggies because they can upset the urinary pH balance.

My FLUTD cat eats Innova EVO and has been doing great on it. It's a dry kibble, not raw, but is grain-free. I would say the key is to eliminate grains, because a high-protein low-carb diet will make his urine acidic and reduce or eliminate the formation of crystals. I always soak my cat's dry food in hot water for a few minutes before feeding to help him get the water he needs. You should also put him on Cosequin for Cats. It's a supplement of glucosamine and chondroitin that is for the joints, but it also forms a slippery barrier on the inside of the bladder to prevent irritation.
